AMT Senors in Shandong Steel Group

[Rizhao, ShanDong, China – May 22, 2025] – Shandong Steel Group, one of China's leading steel manufacturers, is successfully leveraging state-of-the-art AMT (Advanced Measurement Technology) magnetostrictive sensors to optimize critical processes within its crude steel smelting operations. This strategic implementation underscores the company's commitment to technological advancement, aiming to boost efficiency, precision, and safety in the demanding environment of steel production.

Crude steel smelting is a complex, high-temperature process that demands exacting control over material handling and positioning. Traditional sensing technologies often struggle to deliver consistent accuracy and durability amidst harsh conditions characterized by extreme heat, dust, vibration, and strong electromagnetic interference. Recognizing these challenges, Shandong Steel Group has turned to AMT magnetostrictive sensor technology for its superior performance and resilience.

AMT magnetostrictive sensors offer non-contact, absolute position measurement, making them ideal for a range of applications in steel mills. Their robust construction ensures reliable operation even when exposed to the punishing environment of a steel plant. At Shandong Steel's facilities, these sensors are being deployed in several key areas of the crude steel smelting and subsequent handling processes:

1. Ladle Turret and Transfer Car Positioning: Precise positioning of massive ladles filled with molten steel is crucial for safe and efficient teeming into tundishes or continuous casting molds. AMT sensors provide accurate feedback on ladle turret rotation and transfer car location, ensuring millimeter-level accuracy, minimizing spillage, and optimizing cycle times.

2. Tundish Level Control & Car Positioning: Maintaining an optimal and stable molten steel level in the tundish is vital for consistent flow to the continuous caster and for steel quality. AMT sensors are used for precise tundish car positioning and can also be integrated into systems monitoring the molten steel level, contributing to smoother casting operations.

3. Mold Level Control in Continuous Casting: While directly following smelting, the continuous casting process benefits immensely. AMT sensors are employed for highly accurate mold level measurement. Precise control of the molten steel level in the mold is critical for preventing breakouts and ensuring the surface quality of the cast slabs, billets, or blooms.

4. Actuator Position Feedback: Various hydraulic and electromechanical actuators, such as those controlling slide gates on ladles and tundishes, or ladle tilting mechanisms, require precise position feedback. AMT magnetostrictive sensors provide real-time, accurate data, enabling closed-loop control for improved flow regulation and operational safety.

The adoption of AMT magnetostrictive sensors has yielded significant benefits for Shandong Steel Group, including:

● Enhanced Precision: Leading to improved process control, reduced material waste, and higher quality steel products.

● Increased Operational Efficiency: Faster and more accurate positioning reduces cycle times and optimizes throughput.

● Improved Reliability and Reduced Downtime: The durability of magnetostrictive sensors in harsh environments means fewer failures, less maintenance, and greater operational uptime.

● Enhanced Safety: Automation and precise control minimize the need for manual intervention in hazardous areas, improving overall plant safety.

"The integration of AMT magnetostrictive sensor technology is a key part of our ongoing efforts to modernize our steelmaking facilities and embrace smart manufacturing principles," said a representative from Shandong Steel Group's engineering department. "The accuracy and reliability of these sensors in the challenging conditions of our smelting operations have already demonstrated tangible improvements in efficiency and control."

Shandong Steel Group's successful implementation of AMT magnetostrictive sensors sets a strong precedent for the wider adoption of advanced sensor technologies in the steel industry. As steelmakers continue to seek ways to enhance productivity, quality, and sustainability, robust and precise measurement solutions like those provided by AMT will play an increasingly vital role.
